At Thesun Industry, a precision manufacturer and factory specializing in elastomeric flow-control components, we produce high-performance umbrella check valves (often called mushroom valves) for medical devices, consumer products, and industrial fluid systems. This guide explains why mushroom valves deform, how material choice and design prevent failure, and why Liquid Silicone Rubber (LSR) umbrella valves are […]
At Thesun Industry, a precision manufacturer and factory offering one-stop service and tailored custom service solutions, micro machining is a core capability we use to turn demanding designs into high-quality, production-ready components. This guide explains what micro machining is, how it evolved, which processes work best, and how you choose the right equipment and quality […]
Are you evaluating one-way valve options for a medical device, micro-pump, condiment dispenser, or portable consumer product? At Thesun Industry we design and manufacture custom silicone duckbill valves using precision liquid silicone rubber injection molding (LSR). This guide, written from a manufacturer’s perspective, explains what duckbill valves are, where they shine, their core advantages, and […]
Insert molding — also called insert overmolding or metal-to-plastic molding — fuses discrete components (inserts) into molded plastic in a single automated cycle. It’s a powerful approach for producing robust, assembly-free parts that combine the strength of machined inserts or stamped metals with the geometry and sealing of molded polymers. At Thesun Industry we run […]
Are you evaluating replacement seals for an engine rebuild or qualifying a new supplier for production gasket kits? At Thesun Industry we design and manufacture custom valve cover gaskets (also called rocker-cover seals, cam-cover gaskets, or engine cover gaskets) and provide turnkey, traceable custom service from material selection through volume production. This guide explains what […]
Are you evaluating finishing options for high-precision components and wondering whether precision grinding is the right step in your process chain? At Thesun Industry, our factory handles grinding as part of a full one-stop service — from stamping and heat treat through finishing and assembly — and we work closely with customers and suppliers to […]
Valves play a critical role in fluid systems, controlling the flow of liquids, gases, or slurries to ensure optimal operation and safety. Whether used in industrial pipelines, medical devices, or consumer products, valves are essential for maintaining the correct pressure, preventing backflow, and regulating flow rates. Understanding the types, operation, and materials of valves is […]
When OEM engineers and product developers evaluate fluid or air control components, the smallest parts often determine the success or failure of the entire system. At Thesun Industry, we work closely with global OEM customers who face recurring challenges such as leakage, inconsistent cracking pressure, noise, and premature valve failure. One question we hear repeatedly […]
Thanks — glad you asked. At Thesun Industry we treat side milling not as a routine operation but as a precision capability that often determines whether a component meets fit, form, and function in the field. Below is a professional, manufacturer-level guide to side milling: what it is, how it works, the equipment and parameters […]
Looking to guarantee flawless overmolding results for your next product? Great — you’ve come to the right place. At Thesun Industry we design and build high-precision overmolding tools every week, and we know that the difference between an “okay” part and a world-class assembly almost always comes down to mold design, machining discipline, and a […]
